Aston Villa's Jack Grealish tussles with Liverpool's Emre Can in the FA Cup semi-final at Wembley on 19 AprilReuters

Midfielder Jack Grealish who played a crucial role in Aston Villa's FA Cup semi-final win over Liverpool, has become the latest young football star to be photographed allegedly getting high on 'hippy crack'.

The 19-year-old has been photographed inhaling from a white balloon believed to be filled with nitrous oxide — more commonly known as laughing gas, a report in The Sun claims.

According to The Sun, the selfie — which shows Grealish and a friend — was taken in a hotel room about six months ago following a night out.

Grealish is the third Premier League starlet this month to be exposed apparently using the legal high, after Liverpool's Raheem Sterling, 20, and West Bromwich Albion forward Saido Berahino, 21, were both pictured sucking from balloons.
